The Defined Logic component is an 8-pin logic and interface device that replaces traditional relays and diode (Boolean) logic currently used to generate “conditional” logic applications. Defined Logic can be integrated in a VIVISUN® High Capacity switch body or can be included in a stand-alone NEXSYS® LOGIC Module for use behind the panel.
The Defined Logic contains an integrated electrical circuit that is configured to a defined (Boolean) logical function. The output will change state to either ground (0) or high impedance (1) when the defined input condition(s) is/are present.
Defined Logic is available in 4 distinct variations. Each of the variations contains 4 inputs (A – D) and 2 outputs (Y and Z). See overview diagram (right). In each of the variations, the designer must also specify the default polarity of inputs A and C. The unit is factory configured at time of manufacture to the desired variation and logic level.
To help system designers understand the potential of LOGIC Component Technology, we have assembled a collection of Application Notes. The links below show example applications that utilize the Defined Logic component.
